That shouldn't cause any problems, but it's something that needs to be fixed at some point. > The best screen resolution is properly selected on both of my screens, > but the frame-buffer is sized to 640x480.

Currently the resolution has to be configured by the user manually. I haven't tried, but I think giving the resolution with boot parameters should also work. Mythri, have you tried that? I don't think it is possible for the omapdss, panel or omapfb drivers to configure the resolution automatically, except at boot time. After we have booted up, there may be users for the framebuffer and changing it "secretly" would cause problems. I think the best way here is that the HDMI/omapdss driver gives hotplug event, which is conveyed through omapfb to an userspace application. This application can then query the available resolutions via some mechanism, and select one of those. > Fyi, I have also tested with the patches for DVI support and can get > both outputs working simultaneously (my tree is here: > http://dev.omapzoom.org/?p=sebjan/kernel.git;a=shortlog;h=refs/tags/topic-display-iv1-2.6.38-rc7). Thanks. I'll also set up a "test" branch in DSS2 tree shortly, to which I'll add DVI and HDMI patches for easier testing.
